Specification of Letters Patent.

Application filed March 1, 1909.

To all whom it may concern:

Be it known that we, JAMES E. LOOKWOOD and EDWARD Snrrz, citizens of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Vapor-Conduits; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention pertains to a new form of conduit for carrying combustible vapors or gases and relates more particularly to a conduit for conveying combustible vapors or gases to vapor lamps and lamp systems although applicable as well to other purposes.

An object of the invention is to provide a conduit made up of sheet metal sections to be assembled when needed at the place or places where lighting systems are to be in stalled and which in this form has the advantage that the parts may be shipped to a distance, like parts being readily nested so as to ship without damage so that but little shipping space is necessary.

Another object is to provide a conduit in separate sections or portions whereby like portions may be nested so that large quantities of stock can be stored in a comparatively small space.

Another and important object is to construct a vapor conduit in separate parts that can be readily assembled and to provide a conduit that will be low in cost of manufacture.

Another object is to provide a conduit whose parts can be stamped or rolled into the desired form in any small shop where ordinary piping could not be made.

Another object is to provide an ornamental conduit particularly adapted, by rea son of its ornamentation, for installing vapor lighting systems in buildings and wherein the usual disfiguring appearance will be absent.

A further object is to provide an ornamental conduit for ceilings so constructed and arranged that the ceiling may be divided into panels which will give the appearance of ornamentation rather than utility.

To the end that our invention may be understood the accompanying drawing has been provided in which Figure l is a transverse section of one form of a conduit shown in position against a ceiling. Fig. 2 is a transverse section of a slightly different form. Fig. 3 is a perspective View of parts used in constructing another form of conduit. Fig. 4: is a transverse section of an ornamental covering for a conduit. Fig. 5 is a transverse section of a modified form of conduit. Fig. 6 is a perspective view of another form, Fig. 7 is a plan of a portion of a conduit shown against a ceiling with intersecting false conduits associated therewith for dividing the ceiling into panels. Fig. 8 is a perspective View of one of the forms of conduit showing the manner of adjoining false portions with the conduit.

We are aware that conduit sections have been rolled from sheet metal and used for holding and concealing electric Wires but these are, for the most part, quite conspicuous and in fact are not vapor tight and in fact are not fitted for that purpose since there is no provision for the accommodation of pipes leading directly to and for supplying the lamps.

Our structure is novel in that theparts of the conduit can be made from sheet metal and assembled at the place of installation and piping leading to'the lamps can be attached without necessarily using solder or at least the pipe need not be soldered to the conduit as is usually done with sheet metal tubing.

In the several figures A indicates a strip preferably rolled from sheet metal and having any desired form of ornamentation such, for instance, as a series of longitudinal beads as shown in Figs. 3 and 6 gradually diminishing in size toward the outer edges but any other form of ornament may be adopted. This strip may have a central fiat portion B as shown in some of the figures either formed therewith or-secured thereto. This forms the foundation of the conduit and is secured to the ceiling in any good manner but the means therefor is not shown. We have shown in Figs. 1, 2, 3, 5 and 6 some of the different forms that may be used but there are many other forms that could also be used. We next provide a portion G which may be smooth or corrugated, or provided with ornamentation to suit the fancy, and this is suitably secured to the part B by any suitable method as for instance by soldering or swaging or other means whereby tightr joints areassured. We have shown. in'Fig. 3, for instance, a convenient method of connecting or joining the .parts. The portion Athere'in' is provided with bends to form the oppositely disposed TGCGSEQS'D to receive the projecting edges E of the part C the latter being inserted into and pushed alongthe recesses, the metal being after ward clenched upon the said-edges by pressure. As another means for fastening we" have shown for instance in Figs. '1, 2 and 8 a series 'of projections indicated at F -on the part C to extend through aperturesG of the part A which are turned over as shown after which soldering may be resorted toto-obtain a tight joint.

There are several different ways by which 'wemay connect the lamp or other fixture with the conduit .and we have shown severalinthe, drawlng. 'One manner in which this'may be done isshown 1n.Figs. :1 and 3 in'whi'ch we provide a plate H which may be ieitherfsecured to .thepart C -or merely rest..thereinand provided with a threaded hole J,:Fig. 8, into which a 'nipple or pipe K may be screwed. The latter hasan aperture L at diametrically opposite sides, but

one of whichis shown, into which-thevapor' from 'the conduit may enter to pass to" the lamp which said pipe carries 'but not shown. In Fig. 2 weshow a second method in which saidnipple is screwedjinto the part A therebyidispensing with the plate G but other methods may be employed.

' Fig. 6 shows a modification of the conduit in whichthe part A is'provided Withsa shoulder-Bat two places upon which restsaplate C which :may be soldered or otherwisesecured in place to form a tight joint.

Fig. 7L-indicates the :manner in which the ceiling when pro-vided with the vapor conduit maybe divided into panels. The conduit portion C which corresponds with that form shown "in Fig. 8- extends entirely :across the a already been explained with regard to Fig.

6 or it maybe nsed to cover a separate conduit Fig. 4: thereby obtaining the ornamental efiiect on the'ceiling; in either case it being our purpose as herein stated :to provide an ornamentalportion by which a conduit is disguised and made toap'pear as being merely an ornament-and apparently having 'noutility. Y

it is noted that the metal olt the-part *C which is comparatively thin would not be suflicientlystrong,perhapstosupport a lamp tending through or at .leastavouldlnotebe .thio'kenongh to recelve more than a thread or two so that we provide the plate H whichisthick enough for all purposes and merely let this rest upon the said part C, withoutthe necessity of perforating the latter in order to aid in supporting said plate.

Itis our preference in making the conduit to rather broaden and flatten it so that it will depend from the ceiling but a short distance so as to presentaswneatran appearance as :possible, being broadened in order to maintain the needed carrying capacity.

The advantages of our form of conduit are several: First, :it can be manufactured at a much lower cost than tubing or piping since it requires no special machinery but merely light rolls of .a form that will impart the desired shape; second, *that in shipping the parts can be nested so as to occupylitt-le space makingrthe freight'charges less and struction a base portion anda covering portion to interlock therewith, there being a space between them for vapor, a member lying freely withinthe space and upon the covering member and a suspended pipe exthecovering and engaging the said-member. g V

2. A conduit for a-combustible vapor comprising a trough-shaped portion, a base to which it is secured an vapor-tight manner, said base being substantially flat in general form, its edges extending an-appreciable distance each side of the said portion, there being a threaded aperture in said portion, a threa ded pipe toengage the threads of said aperture and a member" within and lyin freely upon the portion and having the sai pipe in engagement therewith.

3. A vapor conduit comprising a troughshaped portion of rolled sheet metal, a substantially fiat base also of rolled sheet metal to'which the portion is secured in a vaportight manner, therebeing a threaded aperture in the saidportion, a 'threaded pipe to engage the aperture and suspended from" the conduit and having-communication with its interior, and a member within and lying freely upon the portionand having the pipe in engagement therewith :held at its upper end with-in said conduit.

4. A vapor conduit comprising a base sub stantially fiat in form, atrough-shaped por-' tion secured to the base vapor tight, saidportion being provided with an aperture, a pipe extending through saidaperture into theconduit, a member within and :lying freelyupon the portion and provided with an aperture to coincide with that of the said portion and having the upper portion of the pipe in threaded engagement therewith.

5. A vapor conduit consisting of a longitudinal substantially flat base provided between its longitudinal edges with two oppositely positioned longitudinal recesses to form receiving guides, a portion adapted to enter said recesses, there being a recess provided between the base and said portion, there also being an aperture in said portion, a member lying within the last named recess, and a pipe extending through said aperture and in engagement with the member.

A vapor conduit comprising a substantially fiat base having a central raised part, there being a longitudinal recess in each margin of said raised part, a member having a depending portion to form a recess for vapor and adapted to enter and lie in the recesses, there being an aperture in the depending portion of said member, a second member lying freely upon the first Within the vapor recess, and a pipe to engage the said second member and communicating with the said vapor process.
